Abstract
Description
Technical Field
[0001] The utility model relates to the field of lithium battery processing equipment, in particular to an experimental sample laser cleaning equipment compatible with multiple lithium batteries. Background Art
[0002] Lithium batteries usually have two shapes: cylindrical and square. The corresponding square lithium batteries are also divided into blade batteries and rectangular batteries (currently the mainstream specifications on the market). However, in the actual R&D and testing stage, there will be a comparative data for the test of the insulating paint surface of lithium batteries, so as to obtain test parameters of different dimensions, thereby improving the safety of lithium batteries.
[0003] In lithium battery production, in order to ensure the relative parameters of its insulating paint surface (such as friction, cleanliness, processing time, etc.), the surface of the insulating layer needs to be cleaned. However, the existing cleaning method is generally for individual lithium batteries. Therefore, due to changes in parameters such as the power, debugging and positioning of the laser device, there will be relative differences in the parameters after cleaning, which affects the stability of subsequent processing (thereby obtaining basic data for optimizing the actual production process). Utility Model Content

[0007] A longitudinal movable frame is provided with a base, and three groups of jigs are provided on the base at intervals. The jigs are detachably arranged on the base, and the three groups of jigs include a cylindrical battery jig, a rectangular battery jig and a blade battery jig.
[0008] In the actual design, a horizontal moving frame, a vertical moving frame and a longitudinal moving frame are respectively arranged on the gantry and the base, so that the travel of the lithium battery and the laser emitting device is simpler and the volume is smaller, avoiding the problem of large volume and large structure of the existing three-axis moving frame, that is, in actual work, after the laser emitting device moves to the specified position, when the insulating layer on the surface needs to be cleaned by laser, the lithium battery moves but the laser emitter does not move, thereby reducing the light deviation error caused by the movement of the laser generator;

The vertical frame 30 is provided with a vertical screw rod pair 33 matched with the vertical slider, and the laser emitting device 5 is provided on the vertical slider. The screw rod driving mode is adopted to ensure the stable operation of the laser emitting device 5.
[0029] In the embodiment of the utility model, the longitudinal moving frame 4 includes four groups of longitudinal guide rails 41 arranged at intervals on the base, a longitudinal slider slidably mounted on the longitudinal guide rails 41, and a longitudinal screw pair 42 for driving the longitudinal slider to move.
